Stari telefon.

Pogled na policu sa knjigama i starim telefonom.
Telefon (iz grckog: tele sto znaci "udaljen" i "fon" sto znaci zvuk) je uredjaj za komunikaciju na daljinu, koji se koristi tako što prima i prenosi ljudski glas sa jednog mjesta na drugo i obratno. Vecina telefona radi tako sto prenosi elektricni signal preko slozenog sistema telefonskih mreza koji dozvoljava komunikaciju skoro bilo kojeg korisnika telefona sa skoro bilo kojim drugim.
U najosnovnijem obliku telefona, zvuk se pretvara u elektricne oscilacije putem mikrofona spojenog u strujni krug. Ove oscilacije se prenose elektricnim provodnikom do slusalice, koja elektricne oscilacije pretvara opet u zvuk.
Telefon je star oko 60 godina, ispravan je i dobro radi, koristi se kad nestane struja.



Old phone.

A view of a bookshelf and an old telephone.
A telephone (from the Greek: calf meaning “distant” and “background” meaning sound) is a remote communication device, used to receive and transmit a human voice from one place to another and vice versa. Most phones work by transmitting an electrical signal over a complex system of telephone networks that allows almost any phone user to communicate with almost anyone else.
In the most basic form of a phone, sound is converted into electrical oscillations via a microphone connected in a circuit. These oscillations are transmitted by an electrical conductor to the handset, which converts the electrical oscillations back into sound.
The phone is about 60 years old, it is correct and works well, it is used when the power goes out.
